When I try to find an old thread here in the community, the results tend to list only two or three threads, not all that match the search crteria. Why is it so limited?

My workaround has been to use open Google search with the statement

in:community.isc2.org as the initial statement, followed by the desired search terms. 

For instance, compare an internal search result as

https://community.isc2.org/t5/forums/searchpage/tab/message?advanced=false&allow_punctuation=false&q...

with the Google search at

https://www.google.com/search?ei=RX7jW7ca46H9Bs2DtPgI&q=in%3Acommunity.isc2.org+censor&oq=in%3Acommu...
